Chemical Structure

Fluoromethane- CAS 20666-44-8 chemical structure

Description

The occurrence of Fluoromethane- is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Fluoromethane- (CAS 20666-44-8), molecular formula [13C]H3F and molecular weight 35.03 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Fluoromethane- ([13C]H3F) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
